Can you beat Call of Duty without committing a war crime?

From Call of Duty Warzone 2 to Rainbow Six Siege and Fortnite, the International Committee of the Red Cross (ICRC) is challenging FPS game players to try to avoid committing any war crimes – or rather, performing any in-game acts that would be considered war crimes in reality. Issuing a bullet-point list of the rules of war, the ICRC says that how you play shooters “makes a difference on the battlefield IRL.” So what do you think? Could you play CoD, Tarkov, or PUBG without committing a war crime?

“Every day, people play games set in conflict zones right from their couch,” the ICRC says. “But right now, armed conflicts are more prevalent than ever. And to the people suffering from their effects, this conflict is not a game. It destroys lives and leaves communities devastated. Therefore, we’re challenging you to play FPS by the real rules of war, to show everyone that even wars have rules – rules which protect humanity on battlefields IRL.”

So, what do you need to do? The ICRC lays down four basic tenets for ethical FPS behaviour.

Firstly, no thirsting. Essentially, this means that if an enemy is on the ground, wounded, and cannot respond, you cannot continue to shoot at them.

Secondly, you can’t attack non-violent NPCs. Any bot that does not fire on you unprovoked is considered a civilian, and therefore cannot be harmed. You also, as a third rule, cannot target any civilian buildings. Houses, schools, and hospitals are all considered safe zones that you must either avoid damaging or not enter whatsoever.
